This is due to stricter bptr checks added in 2.3.2 [1]. It means that your on-disk
zfs structure is somehow corrupted logically, but not a problem introduced by 2.3.2.
This might come from bugs in zfs code, or even cosmic ray (if you do not have ECC memory).

I would recommend running a scrub on your pool with a previous version, or even better,
recreate the dataset totally (by zfs send | zfs recv).
